User Terminal and Radio Communication Method

1. A terminal comprising: a receiver that receives downlink control information; and a processor that determines, based on an RNTI applied to a cyclic redundancy check (CRC) on the downlink control information and a bit value in a plurality of fields included in the downlink control information, whether to activate or deactivate channel state information reporting.

2. The terminal according to claim 1 , wherein the receiver receives the downlink control information by using a UE-specific search space.

3. The terminal according to claim 2 , wherein the processor determines, based on a bit value in at least a resource assignment field included in the downlink control information, to deactivate the channel state information reporting.

4. The terminal according to claim 1 , wherein the processor determines, based on a bit value in at least a resource assignment field included in the downlink control information, to deactivate the channel state information reporting.

5. A radio communication method for a terminal, comprising: receiving downlink control information; and determining, based on an RNTI applied to a cyclic redundancy check (CRC) on the downlink control information and a bit value in a plurality of fields included in the downlink control information, whether to activate or deactivate channel state information reporting.

6. A base station comprising: a transmitter that transmits downlink control information; and a processor that controls to determine, based on an RNTI applied to a cyclic redundancy check (CRC) on the downlink control information and a bit value in a plurality of fields included in the downlink control information, whether to activate or deactivate channel state information reporting.

7. A system comprising a base station and a terminal, wherein: the base station comprises: a transmitter that transmits downlink control information; and a processor of the base station that controls to determine, based on an RNTI applied to a cyclic redundancy check (CRC) on the downlink control information and a bit value in a plurality of fields included in the downlink control information, whether to activate or deactivate channel state information reporting, and the terminal comprises: a receiver that receives the downlink control information; and a processor of the terminal that determines, based on the RNTI applied to the CRC on the downlink control information and the bit value in the plurality of fields included in the downlink control information, whether to activate or deactivate channel state information reporting.
